Improvement in liquid-meters



UNITEDA STAT-Els PATENT i ANNA BTTN ER, ADMINI STRATRIX OF THE ESTATE OFFRIEDRICH BTTN-ER, DEOEASED, OFA NEW YORK, N. Y.

IMPROVEMENT. IN LIQUID-METERS.

Specilication forming part of Letters Patent No. 113.017,'dated March28, 1871.

To all whom it may concern:

Be it known that FRIEDRICH BTTNER, deceased, late of the city of NewYork, in the county and Stateof New York, did, during his life-time,invent a new and Improved Liquid Meter; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing v had to the accompanying drawing, forming part of thisspecilication.

Figure l represents a vertical longitudinal section of the improvedliquid-meter. Fig. 2 is a plan or top view of the same. Fig. 3 is avertical transverse section of the same, w a', Fig. 1, being thesection-line.

Similar letters of reference indicate correspondin g parts. 5

This invention relates to liquid-meters; and consists in certainimprovements thereon, which will be iirst described in connection withall that is necessary to a full understanding thereof, and then clearlyspecified in the claim.

A in the drawing represents a box or chest, of quadrangular orothersuitable form, provided with a false bottom, a, and divided above saidfalse bottom into two equal parts or chambers, b o, by means of atransverse partition, f.

The bottom of each chamber b o has one aperture, d, leading to the lowerchamber, e, under the false bottom, where the discharge-pipe is applied.

B B are valves for closing the apertures d, they being suspended fromthe ends of a'beam, O, which is pivoted by a pin or shaft, h, to thesides of the box A. To the beam is secured, or with it is connected, apla-te, D, which covers part of the box A, as shown.

Within the center of each chamber b c is set up a fixed post or pin, t',on which a tloat, E, is allowed to slide up and down. i

F is a small longitudinal box, pivoted in the box A by a pin, j, whichis parallel with the pivot h ofthe beam C, and directly above thepartition f. The box F is thus under the beam G. It is partly filledwith quicksilver, which serves to hold it in an inclined position.

G is the stationary trough for conveying the liquid to the chambers b o.It is higher in the middle, its lower open ends being respectively abovethe chambers b c, and has a transverse partition across its highestpart. Above it is pivoted the distributing-trough H, which extends'across the upper part ofthe box A, but has an opening for the dischargeof the liquid only above the trough G. 1

The trough H is pivoted at its ends, so that it can swing to be inclinedto either side. It

is, by means of forked arms l, or equivalent devices, connected with thebeam C, so as to be moved by the same.

The operation is as follows: The water or other liquid to be measured isallowed to flow' into the trough H, and is, by the opening in the same,discharged into that end of the trough G which is above the loweredvalve B, the trough H hanging so inclined as to discharge the liquidonly in the desired direction.

In the drawing the positions of the trough H and beam C are shown to besuch that the water will flow to the chamber c, whose valve is closed.As the water rises in said chamber it will gradually elevate the float Euntil the same strikes the lower end of the vessel F.

When the chamber c has been filled to the desired height the float hasbeen raised against the vessel F so as to tip the same over-z'. e.,inclineit to the other side-which motion,when the start is once given,is rapidly completed by the quickly-movin g mercury.

The vessel F inv swinging strikes with its elevated end against thelower end of the beam C, and swings the same over in the same manner, soas to open the valve in c and close that in b.

The same motion of the beam swings the trough H, so that the liquid willbe discharged into the vessel b, while from c it will flow out throughthe opening d. There is thus a rapid change in the position of thedistributingtrough and valves to change the liow of the liquid from c tod, and vice versa, as soon as the requisite quantity is in either.

By means of an arm on the rocking trough H, or on the pin h, motion canbe imparted to va pawl, m, by which it is transmitted to aratchet-wheel, n, and thence to a series of indicators or pointers, o o,in the ordinary or suitable manner.

Each valve B has the greater part of its sury face covered by a pipe orhollow case, p, which projects above the Height to which the liquidrises, so that thereby the liquid is prevented from weighting the valveand obstructing its elevation. v

Having thus described the invention of FRIEDRICH BTTNER, deceased, Iclaim as new and desireto secure by Letters Patent- A oase, p, appliedas described to the valve B,for the purpose of' preventing the latterfrom being Weighted by the liquid.
